ROLLER-BEARING.

Be it known that I, JOHN JACOB, a citizen of the United States, and a resident of Chi- I cage, in the county of Cook and State of Illi- Fi 1, tiO I'I of a slightly modified form of the beari 7 is a transverse sectlon, taken on l1ne-77 ing shown in Big. 5.

. chamber A.

nois, have'invented certain new and useful Improvements in Roller-Bearings; and I do hereby declare that the following is a full,

clear, and-exact description thereof, referones being had to the accompanying drawings, and to the letters of reference marked.

thereon, whi'c'hform a part of this specification;

'- Thlsinvention relates to improvements in roller bearings for railway cars and like purposes and the invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claims.

The objects of the invention are to provide novel construction for retaining the roller in the roller bearing casing and to otherwise improve the general construction of the bearing.

- In the drawings :Figure 1 is a longitudinal, vertical section of a roller bearing embodying my invention. Fig. 2 is a bottom plan 'view thereof, showing the roller at one end of its travel. Fig. 3 is a transverse section, taken on line 3-3 of Fig. 1. Fig. 4 is a detail horizontal section, taken on line 44 of Fig. 5 is a longitudinal vertical see- Fig. 6 is a top plan view thereof. Fig.

of Fig. 5. Fi 8 is an end view of the bear- My improvements are herein shown as applied to roller side bearings for railway cars, wherein the bearing roller is contained in a casing which is adapted to be attached to and to depend from the end of the car bolster and through the lower open side of the roller chamber of which the roller projects for contact with an upwardly facing bearing on' the truck. As will be obvious, however, my invention may be variously adapted to other types of roller bearing of the same general character for this and analogous uses.

As shown in said drawings, A designates, as a'whole,'the upper bearing member of the type of bearing referred to, comprising a castmetal casin formed to provide a down-' wardly opeiiin orizontally elongated,roller designates a'cylindricbearing roller located in said chamber, which Specification of Letters Patent.

is adapted for rolling contact with a downwardl facing bearing surface at the top of said c amber and ro ects through the lower open side of thee amber for contact with a lower bearing surface, indicated by the line C;

The said casmg shown in Figs. 1 to 4, comprises a top wall a, sidewalls a a and end walls a o The side walls are formed to provide on their inner faces elongated channels or recesses A which receive the trunnions or end bearings b of the roller B. The bottom walls a of said channels constitute tracks that support the roller B, through the medium of said trunnions, when the roller is out of engagement with the upper and lowerbearing surfaces. The said tracks are shown as inclined inwardly and downwardly towards thelongitudinal center of the casing to automatically center the roller in the easing when it is supported by said tracks, as is common in this type of bearing. Said casing is provided at its ends with oppositely extending apertured lugs a by WhlCh the casingzis attached to the bolster or other part which carries the same.

The downwardly facing bearing surface in the upper art of the roller chamber comprises the ownwardly facing surface (1 of a removable hard-metal wear-plate D that is fitted to the top and end walls of the casing in the same general manner as shown in the prior ap lication for United States Letters Patent lied by myself and Edwin S. Woods, on August 4th, 1906, Serial Number 329,233. The top wall of the casing is provided with a horizontal groove a which receives the central or horizontal portion of the wearplate D and the end walls of the casing are provided with like grooves a .a to receive the curved end portions (1 of said plate. Said removable Wear-plate D comprises a central horizontal ortion, and downwardly curved ends (1 d which are so disposed as to constitute curved stops to arrest the travel of the roller in the same manner as shown in the aforesaid application. a v

In accordance with my invention the roller is inserted into the roller chamber through a suitable opening between the side walls f the ca..in and the wear-plate D is therea ter inserte into the casing between said roller and te top wall of the casing in a manner to con titute a locking device to confine the rolle \in thecasmg, it being net:-

essary to remove the wear-plate in order to remove the roller. In the resent construc' tion the roller is inserted? into the roller chamber through the opening at the lower side thereof, through which the roller projects forcontact with the lower bearing (1. The "track flanges at the lower margins of the side walls of the casing are cut away near the ends of 'the casing to provide notchesa a. through which'the trunnions of the roller ass when the rolleris inserted into the easmg. The said notches are located at such distance from one endwall a of the casing that the distance between the inner end walls of said notches and the adjacent 'end wall of the casing is slightly greater than the distance between the periphery of the roller and the curved faces of the trunnions at points remote from the point on the periphcry from which the measurement is taken. This arrangement permits the roller to be inserted freely into the casing and the trunnions to pass through said notches in the track flanges at a time when the wear-plate is removed'from' the casing. Thereafter the wear plate is. inserted into said chamber through the end thereof adjacent to the said notches. \Vhen the said wear-plate is in place the end thereof adjacent to the trunnion receiving notches constitutes a lock which prevents the removal of the roller so long as said plate is in place. That is to say, the distance between the inner face of said curved end of the wear plate, and the inner ends of the trunnion receiving notches, is so short that when the eri hery of the roller engages said end of t ie p ate, the trunnions are not free to pass through said notches, as clearly shown in Fig. 2.

In constructions where the bearing mem her is reversed from the position shown to present the roller to a downwardly facing caring surface, no special means are required to lock the Wear-plate in place. When, however, the said bearing member is disposed to present the roller to an upwardly.

facing bearing surface, any suitable means are employed for lockmg said wear-plate from endwise removal from the casing.

Such locking of the wearlate is effected in this instance by means 0 a bolt or rivet E extending through openings in the side walls of the casing and transversely across said casing in line with the adjacent end face of the wear-plate. The opposite end of the, wear-plate engages an upwardly facing shoulder a on the adjacent end wall of the casing which holds the end of the plate in place. A readily removable locking device for the wearlate is preferred, inasmuch as it simplifies t 1e dismemherment of the bearing when desired. Such dismemberment,of the bearing is effected by removing the rivet E or other locking device. whereupon the wear-plate may be readily withdrawn endwise fromthe casing. ,Thereafter the roller is free to be removed from the casing as is obvious.

In Figs. 5 to 8, inclusive, the upper wall a of the casing is cut away in a plane which intersects the roller bearing chamber throughout aportion of its length, thus producing a central opening a in said top wall. In this instance, the horizontal. portion of the wear-plate is flush at its upper face wlth the upper face of said top wall and constitutes. a portion of the top wall of the casing. When the bearing member is fixed in place the said upper face of the wear-plate has contact with the lower face of the part to which the bearing is attached, thereby constituting a backing or support for the intermediate or central part of the wear-plate. In'this construction, as in the previously described construction, the curved ends of the wearplate iit against the corres ondingly curved surfaces of the top and en walls of the easing, and said wear-plate is inserted into the casing from one end thereof and is locked therein in the manner before described. This construction last described recommends .itself where the distance between the parts carrying the' two bearings is such as to require a bearing of minimum height. Moreover, said latter construction makes it practicable to introduce the roller through the upper open side of the casing, as shown in my copending application for Letters Patent filed on the 11th day of February 1907, Serial No. 356,780. In' the latter event the track flanges are made continuous or unbroken and the notches through which pass the roller trunnions are formed in He side walls of the casing at the top margins thereof.
